Explanation:
First, lets walk through what each word/number means. Then we can set up an equation and solve.

The word is is synonymous with equals, which is represented in an equation with the equal sign (
#=# ). 
In this problem, 10 can stay the way it is. There is nothing more to be done.

More is another way to say "in addition" or "plus". We will display this in the equation using a plus sign (
#+# ). 
#c# is a variable. 
3 can be left alone.
So our equation would look like this:
#10+c=3#
Using basic math, we can solve this.
#c = 310#
#c = 7#
